Analgesia after laparoscopic sterilisation. Effect of 2% lignocaine gel applied to Filshie clips

We performed a randomised controlled study in patients undergoing day case laparoscopic sterilisation to assess whether coating Filshie clips with 2% lignocaine gel prior to application to the Fallopian tubes would reduce postoperative pain. Sixty-two patients were studied, in 33 of whom the Filshie clips were coated in sterile 2% lignocaine gel. Pain scores in the lignocaine gel group were significantly lower than in the control group at 1 h after return to the ward, but no differences were found immediately on return to the ward, or at discharge or at 24 h. There were no significant differences between the two groups in postoperative analgesic requirements or in side effects.
